摘要： Spline teeth 66 formed in the inner periphery of a sleeve 45 slidably supported on a hub 63 fixed to a rotation shaft each comprise a projecting portion 66a constituted by a first inclined surface &agr;, a flat surface &ggr; and a second inclined surface &bgr;, and these projecting portions 66a bias a blocking ring via a synchro-spring 71 in an axial direction to thereby generte a synchronizing load between the sleeve 45 and a gear 37. Immediately before the projecting portions 66a of the spline teeth 66 of the sleeve 45 moving rightward mesh with dog teeth 37a of the gear 37, the second inclined surfaces &bgr; of the projecting portions 66a move and ride on the synchro-spring 71 so as to gradually reduce a pressing force axially applied to the blocking ring 67, thereby making it possible to provide a smooth mesh engagement between the spline teeth 66 of the sleeve 45 and the dog teeth 37a of the gear 37.
